Answer

In chronic, severe symptomatic hyponatremia, the rate of correction should not exceed 0.5-1 mEq/L/h, with a total increase not to exceed 8-12 mEq/L/d and no more than 18 mEq/L in the first 48 h. The sodium concentration must be corrected to a safe range (usually to no greater than 120 mEq/L) rather than to a normal value. As noted above, spontaneous diuresis secondary to ADH suppression with intravascular volume repletion could lead to unintended overcorrection.
